This 36 hour, 4.5 day training program uses a hands-on approach providing students with a fundamental understanding of industrial process measurement & control systems. Participants will learn the basic measurement & control principles, terminology, symbols & documentation standards. In addition students will perform hands-on exercises with actual industrial temperature, pressure, flow &level measurement & control devices to gain experience in how to set up & troubleshoot a control system.
- Introduction to ISA documentation standards: Process Flow Diagrams (PFD’s), Piping & Instrument Diagrams (P&ID’s), Loop Diagrams, Location Plans & Installation Details
- Test Equipment: Calibrators, Digital Multimeters & Power Supplies
- Signals: Analog – voltage & milliamps, Digital – on/off & digital data, Wiring basics
- Elements of a Process Control Loop: PV-Process Variable, MV-Manipulated Variable & C-Controller
- Temperature Measurement: Thermocouples, RTDs, Thermometers, Infrared, Characteristics, Thermowell & Transmitters
- Pressure Measurement: Gauges, Transmitters & Block & Bleed Valves
- Flow Measurement: DP Meters, Turbine Meters, Pd Meters & Variable Area Meters
- Level Measurement: Float Gauges, Static Head Gauges & Sounding Gauges
- Control Valves: Types, Accessories, Sizing & Basic Troubleshooting
This is an entry level course & requires only that participants be familiar with industrial manufacturing processes.
